EVAL BOARD , LIGHTING, LED DRIVER

80W-1A primary side current loop control LED driver with STCH03 is a demonstration board for street lighting applications with a primary current sensing control loop. The LED driver is a fixed current source with a very fast start-up time, protections to short-circuit and to open load. The board is optimized to supply an LED string load in the range from 40V to 80V with a fixed 1A current source with a very low current ripple. Due to current primary side STCH03 control loop, the output stage is composed of a simple diode rectification and the output capacitor. Form factor is compatible with street lighting application. At full load the efficiency is above the 90% at nominal voltages and remains very close to this value till half the load. Output short-circuit and no-load protections are auto-restart for a safe operation in lighting environment. Low input power is there at no-load conditions.
